梯度功能材料热应力缓和优化设计

Optimization Design on Lessening Heat Stresses of Functionally Graded Materials

在研究梯度功能材料效应力缓和优化问题时，提出了一个分析梯度功能材料中间层体积组分规律的关系式．并运用这个关系式．结合优化理论，对效应力缓和梯度功能材料进行了计算，并得出一些对梯度功能材料设计有价值的结论。

This thesis has raised a relative formula to analyse the regularity of coordination and division in the volumn of the middlelevel of functionally graded material while doing research in the decrease and optimization of the thermal stress of functionally gradedmaterial. Furthermore, this essay also applies the relative formula combined with the optimization theory to the calculation in functionally graded material witch decreases thermal stress as well as reaching some conclusions valuable to the design of functionally gradedmaterial.
